What is the purpose of secondary containment for chemical storage?

• A. To hide spills.
• B. Contain leaks or spills to prevent environmental contamination and cross‑contamination between containers.
• C. To label containers more clearly.
• D. To increase chemical reactivity.

Answer: (B)

Secondary containment serves as a backup layer to keep hazardous chemicals from spreading if a container leaks or spills. By placing primary containers in spill trays, secondary containment catches liquids and prevents them from reaching the floor, drains, or nearby containers, which protects the environment and reduces the chance of cross‑contamination between chemicals. This is exactly why it’s described as containing leaks or spills to prevent environmental contamination and cross‑contamination. It’s not meant to hide spills, improve labeling, or increase reactivity, which would be unsafe and counterproductive.
